Title: Marine engine plant
IPC: F01K7/02
Filed: 1933-01-10
Abstract: 396,291. Motor power plant. BAUER, G., 82, Mittelweg, Hamburg, Germany. Jan. 10, 1933, Nos. 858 and 859. Convention dates, June 21, 1932, and Dec. 23, 1932. [Class 110 (iii).] In a marine power plant comprising a compound reciprocating engine and an exhaust steam turbine driving the same propeller shaft and arranged in line the two engines are disposed on a common bed plate, the turbine and its gear which includes an elastic or slip coupling connection are arranged under one another in about the same plane, the valve gear of the reciprocating engine is arranged on the side or end so as not to increase the breadth of the engine, the steam is led out of the intermediate pressure cylinder through a single bend to the exhaust turbine, a switch-over valve is provided between the engine turbine and condenser and takes the form of a disc inside the turbine casing, and a coupling is provided between the propeller shaft and the crank shaft. A compound reciprocating engine 1, and an exhaust turbine 2 with its double reduction gear 3, 3a and thrust block 4 are mounted on a common bed 9. The engine 1 comprises high and intermediate pressure cylinders 10, 11 provided with drop valve gear, the main eccentric, links 13, cam shaft 15 and valve chest 16 being arranged so as not to project beyond the lateral width of the engine. The turbine assembly is behind the engine and coupled by a pipe 5 having one short bend. The switch-over valve 7 is of plate form and normally retained in position by a weight 8. The propeller shaft and the crank shaft are connected by a coupling 6. In a modification slide valve gear is fitted in place of drop valves. If required the auxiliary devices not shown, are provided for supplying steam to the receiver or the top or the bottom of the cylinder during manoeuvring. The various controls used in reversing may be interlocked. In a further modification the cylinders are arranged in V form and set transversely across the driving shaft. The valve gears and drive may then be disposed at the front or back of the engine instead of at the sides. In place of the mechanical valve operation, an oil pressure system may be adopted. The large gear wheel on the transmission system is used in place of the normal means for barring the shaft. Instead of connecting the reciprocating engine directly with the propeller shaft it may also be designed to run faster and be geared down thereto. Further, each stage of the compound engine may be composed of a twin cylinder with cranks at 90‹ and arrangements may be made when reversing to supply high pressure steam to the intermediate cylinder.

Title: Pulverulent synthetic resins and method of preparing the same
IPC: B02C19/18
Filed: 1965-01-08
Abstract: Synthetic resins are powdered by forming foams thereof which are then comminuted to a particle size of 40-325 mesh (U.S.S.). The expansion may be effected mechanically, e.g. by beating gases into or bubbling gases through the molten resin or chemically by the use of volatile liquid or decomposable solid blowing agents (e.g. azobisisobutyronitrile).  With the latter type of blowing agent extrusion processes may be used.  If the product is required to be non-cellular as for fusion-coating processes, care is taken to ensure that the cell size is larger than the final particle size, for example by varying the amount of blowing agent added. During grinding, the resin may be cooled by liquid nitrogen, water or by the atmosphere.  In Example 1 the resin is a PVC composition containing dioctylphthalate plasticizer, epoxidized soya oil, TiO2, CaSO4, Ba and Cd laurates, dibasic Pb phosphate and azodicarbonamide. In Example 2 the resin is nylon 11, and in Example 3 a chlorinated polyether resin.  The products are said to be useful in a number of fusion coating processes such as flame spraying, electrostatic spraying, knife coating, sublimation and fluidized bed processes.

Abstract: PCT No. PCT/GB87/00889 Sec. 371 Date Sep. 26, 1988 Sec. 102(e) Date Sep. 26, 1988 PCT Filed Dec. 8, 1987 PCT Pub. No. WO88/04414 PCT Pub. Date Jun. 16, 1988.A radiation meter for measuring the intensity of incident ultraviolet radiation in a predetermined wavelength band against a background of broadband radiation, such as sunlight, includes a sheet of a material incorporating a fluorescent dye. The dye is selected to absorb radiation in the predetermined wavelength band and consequently to emit fluorescent radiation. The fluorescent radiation is internally reflected within the sheet and emerges from an edge of the sheet, where it impinges on a photodiode. The photodiode produces an output which is dependent upon the intensity of the ultraviolet radiation. This output is used to drive a suitable display. The unwanted background radiation passes through the sheet without causing fluorescence of the dye, and is absorbed in an absorbent backing layer. The photodiode is so positioned and screened that the background radiation cannot impinge upon it. A particularly advantageous use of the meter is for measurement of the intensity of ultraviolet band radiation, which is the cause of sunburn and skin cancer.

Abstract: PROBLEM TO BE SOLVED: To attain an IDDQ test to find out presence of a defective transistor(TR) through the measurement of a power supply current being a very small leakage current in the input circuit employing a sense amplifier having a differential amplifier circuit in which a steady-state current flows even when a logic state is in a steady-state. SOLUTION: Even in the case of a steady-state of a logic state, a power supply current of 100μA or over, or in a case, as high as 1mA flows to a sense amplifier 10. A very small IDDQ current cannot be measured when the power supply current as above is flowing, In the case of the IDDQ test, a power supply current of the sense amplifier 10 is shut off by a test mode signal Q. In the test mode, the operation of the sense amplifier 10 is stopped, a clocked inverter 12 provided in parallel with the sense amplifier 10 is used to receive signal from an input terminal PI. Thus, the IDDQ test pattern is received to make the test convenient.

Filed: 1988-01-07
Abstract: PURPOSE:To conduct a highly precise printing by a method wherein the aligner main body having a mask and a wafer is supported by a fixing guide in such a manner that the displacement other than the surface vertical to an X-ray axis will be restricted. CONSTITUTION:An aligner main body 1 is supported to a fixing part with an air spring 6 in a swingable manner. The main body 1 is supported by a fixing guide 5 in such a manner that the displacement other then the surface vertical to the X-ray axis will be restricted. When the center of gravity of the main body 1 changes, displacement is generated on the spring 6, and the main body inclines. The upper and the lower moving guides 2 and 4 permit the displacement alone within the surface vertical to the optical axis of the main body 1, and the main body 1 is guided by the guides in a highly precise manner. As a result, no positional deviation is generated, and a highly precise printing can be conducted.
